OPPO Unveils 12Mbps Data Rate Bluetooth Wireless Audio SoC at MWC 2023

On the opening day of Mobile World Congress (MWC) 2023 in Barcelona, OPPO announced a selection of flagship devices, new core connectivity products and technologies, as well as its latest R&D breakthroughs in chip technology. On the audio domain, OPPO promised to revolutionize the industry and leave Bluetooth limitations behind with its MariSilicon Y flagship audio SoC. A world first for Bluetooth wireless audio, the new SoC promises a 12Mbps data rate.

In 2022, the Bluetooth Special Interest Group (SIG) announced the Auracast extension of the Bluetooth LE Audio specifications, combining audio sharing and broadcast audio into a new term that would make it easier to promote. The audio innovation promises to propel audio streaming forward by letting users share their audio or select from publicly available Auracast wireless audio streams. At Mobile World Congress (MWC) 2023 in Barcelona the technology was demonstrated in a practical manner for the very first time.

EarFun has launched the new Air Pro 3 true wireless earbuds that are said to be LE Audio-ready. audioXpress has waited until the start of MWC 2023 in Barcelona to see if anyone would dispute or make a similar claim. Since no one did, we can reliably publish the story now. Earfun is now selling the World's 1st LE-audio ANC true wireless earbuds, the brand's new TWS earbud flagship, which uses the Qualcomm QCC 3071 chip, and also supports Bluetooth 5.3, and aptX Adaptive.

IOT747, a Cambridge, UK-based supplier of wireless modules and solutions announced a partnership with AntennaWare, the Northern Ireland-based developer of Bluetooth and Ultra-Wideband (UWB) antenna solutions for wireless wearables. The partnership integrates AntennaWare BodyWave Antenna with the IDC737 Bluetooth module in an example reference design for long-range and wearable applications.

As many audioXpress readers already learned from reading the article by Hans W. Gierlich on the Benefits of Using Structure-Borne Sound in Headset Signal Processing, HEAD acoustics created a complete test solution for in-ear and headset devices using bone-conduction sensors. There are good reasons for developers and manufacturers to explore the use of bone-conduction sensors and test them with the new ViBRIDGE solution.
